Real Madrid and Wales forward Gareth Bale is a doubt for El Clasico against Barcelona after suffering an ankle injury.
The 27-year-old hobbled out of Tuesday’s 2-1 Champions League win at Sporting Lisbon.
Real Madrid confirmed that Bale has a “traumatic dislocation of the peroneal tendons” in his right ankle, but did not state how long he could be out for.
Zinedine Zidane’s side play Barcelona in La Liga on 3 December.
League leaders Real have a four-point advantage over Barca.
Bale has made 20 appearances for club and country since August, scoring 11 goals.
He signed an extension to his contract at Real in October, keeping him at the Spanish giants until 2022.
